DELIVERY MECHANISM FOR ORE-BINS.

SPECIFICATION formingpart of Letters Patent No. 738,076, dated September 1, 1903.

Application filed October 28, 1901. Serial No. 80,267. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN WEIGHT SEAVER, a citizen of the United States, and a resident of Cleveland, Ohio, have invented certain Improvements in Delivery Mechanism for Oreliins, of which the following is a specification.

The object of my invention is to so construct delivery apparatus for ore-bins or other receptacles for granular material as to readily control the rate of discharge and to operate any one or more of a number of delivery devices by means of a single motivepower mechanism.

This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which--- Figure 1 is a side view,partlyin section,of a bin structure with delivery mechanism therefor in accordance with my invention. Fig. 2 is an enlarged section of the spout portion of the bin. Fig. 3 is a front view of said spout. Fig. 4c is a side view of the delivery-belt and of the supporting mechanism therefor. Fig. 5 is an end view of a traveling larry forming part of the delivery mechanism; and Fig. 6 is a plan view of the same, partly broken away.

The bin structure 1 (shown in Fig. 1) is mounted upon a framework comprising vertical columns 2, top girders 3, and lower crossgirders l,the top girders supporting tracks for the cars whereby the ore is conveyed to the bins, it being understood that a series of these bins are located side by side in the supporting structure, each bin having its own delivery apparatus; but as the delivery apparatus is the same for all of the bins it will be necessary to describe but one of them.

The bin has an inclined delivery-spout 5, having a closed bottom and sides but open at the top, and across this spout, some distance above the bottom of the same, passes a bar 6, which is rigidly supported in the spout and has formed in it openings for a nulnberof pins 7, which when inserted extend from the bar to the bottom of the spout and constitute a grated valve for governing the discharge of ore from the bin. These pins 7 may be independent of each other or their outer ends may said bin structure.

be connected, so that they can be moved as a unit. p

Directly beneath the lower end of the delivery-spout is an endless belt 0, Fig. 4, which is mounted upon drums 10 and 11, theshafts of said drums being adapted, respectively, to bearings 12 and 13, carried by opposite side frames 14, which are bolted to longitudinal beams 15, carried by the transverse girders 4E and forming part of the fixed supporting structure of the bin.

The bearings 13 for the shaft of the drum 11 are controlled by an ad j Listing-screw 16, as shown in Fig. 4, so as to keep the belt 9 at a proper tension, and the sagging of the upper run of the belt, which receives and carries the load of ore from the spout 5, is prevented by means of a smooth steel plate 17, which-is interposed directly beneath the upper run of the belt and is secured to and carried by upwardly-projecting central portions of the frames 14:.

The shaft of the drum 10 has a spur-wheel 19, which meshes with a spur-wheel 20 on a shaft carried by bearings depending from the frames 14, power being applied to this spurwheel 20 in order to drive the belt 0 and thereby cause the latter to convey from the discharge end of the spout the ore which is permitted to flow down said spout when the pins 7 or any desired number of the same have been raised.

It will be observed that the conveyer-belt 9 and all of its supporting devices are carried by the frames 14, which are supported upon the fixed structure, so as to be entirely separate from the bin. supporting mechanism can be removed and replaced without disturbing any portion of Ready inspection or repair of the belt mechanism is thereby permitted, and, besides this, erection of the mechanism in the first instance is much facilitated.

By the use in connection with the deliverybelt of an inclined spout, as shown, the bottom of said spout serves to sustain a portion of the weight of the ore after the same passes the valve of the spout and by locating the Hence the belt and its.

valve above the bottom of the spout the belt is entirely relieved from the weight of ore in the bin. Consequently accidents to the belt and its operating mechanism due to overloading are effectually prevented. I do not, however, claim the use of the endless d elivery-belt nor the means for supporting the same, nor do I limit my present invention thereto, as other means for governing the discharge from the bin may be substituted therefor.

The operation of the ore-delivery belt is effected by a motor and gearing on a traveling larry, the rails or runways for which are mounted on longitudinal beams 21 on the fixed structure, as shown in Fig. 1, the construction of this larry being illustrated in Figs. 5 and 6, in which the same is shown in duplex form, although a single larry can be employed, if desired.

An upper framework 22 carries bearings for shafts 23 and 24, which have grooved wheels 25, adapted to the rails or runways on the beams 21, the shaft 24 being driven by suitable gearing from a motor 26, so as to impart traversing movement in either direction to the larry,a friction-brake 27,0perated bya treadle 29, serving to quickly stop the rotation of the gearing, whereby the larry can be accurately adjusted to any desired position longitudinally beneath the row of bins. Another motor 30 drives by means of suitable gearing a longitudinal shaft 31, mounted in bearings 011 the top frame 22 of the larry, and this shaft has spur-wheels 32, with which mesh spurpinions 33, carried by swinging frames 34, hung to the shaft 81, so that each spur-pinion 33 can be moved around its corresponding spur-wheel 32 without interfering with the proper mesh of the two. Each swinging frame 34 is connected by a link 35 to a bell crank lever 36, and the latter is connected by a link 37 to a bell-crank lever 30, which in turn is connected by a link 40 to a treadle 41,suitably located in the cab with which the larry is provided.

lVhen the larry has been adjusted to its proper longitudinal position, the swinging upward of a frame 34: will serve to bring its spur-pinion 33 into mesh with the spur-wheel 20 of the belt-driving gear of one of the bin delivery mechanisms, so as to impart movement to the belt and thereby deliver ore from the bin, the rate of delivery being dependent upon the speed of the belt,assuming,of course, that the grated regulating-valve has first been opened to permit afiow of ore down the spout 5 in suificient quantity.

The material delivered by the belt may be directed to anysuitable point of discharge, or, if desired, the larry may be provided with a bin for receiving the material thus delivered, such bin being shown at 42 in Fig. 5 and being provided with a swinging gate 43, operated by alever n, so that thelarry can convey the load to such point of discharge. If movement is imparted to the larr y without withdrawing the spur-pinion from engagement with the spurwheel 20, such disengagement will be effected by the lateral IHOVGDJQD'D of the pinion 33. Hence there will be no discharge from the bin unless the larry is in position to receive such discharge.

In the larry shown in the drawings two sets of belt-operating gearing are shown, so that the same is adapted forsimultaneously operating two delivery-belts; but of course it will be understood that but one set of gearing need be employed, as the provision for longitudinal movement of the larry enables it to oper- 1 ate any desired one of the delivery-belts by simply adjusting it to position to engage with the gearing of the latter.

Although I have described my invention in connection with ore delivery bins, it will be evident that it can be used in connection with bins for the storage and delivery of any granular material.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. The combination of a storage-bin with an inclined delivery spout having a perforated transverse bar therein, and a series of pins passing through the perforations of said bar and constituting a grated valve for governing the flow through the spout, substantially as specified.

2. The combination of a storage-bin, mechanism for controlling the discharge therefrom, and a traveling larry having a poweroperated shaft and means whereby the rotation of said shaft is caused to operate the discharge mechanism of the bin, substantially as specified.

3. The combination of a storage-bin, mechanism controlling the discharge therefrom and having as an element a toothed gear, and a traveling larryhaving a pinionfor engaging said toothed gear and means for rotating said pinion, substantially as specified.

4:. lhe combination of a storage-bin, mechanism governing the discharge therefrom and having as an element a toothed gear, and a traveling larry having a pinion for engaging said gear and means for operating said pinion, the traveling movement of the larry being such as to carry its pinion laterally into and out of engagement with the toothed gear of the delivery mechanism of the bin, substantially as specified.

5'. The combination of a storage-bin, mechanism governing the discharge therefrom and having as an element a toothed gear, a traveling larry having a pinion for engaging said gear, said pinion being so mounted on the larry as to be movable in and out of meshwith the gear, and means on the larry for operating said pinion, substantially as specified.

6. The combination of a storage-bin, mechanism governing the discharge therefrom and having as an element a toothed gear, a a traveling larry having means for operating traveling larry having a motor and a shaft driven thereby, a frame swinging on said shaft and carrying a pinion meshing with a spurwheel on the shaft, and means for swinging said frame, whereby its pinion may be moved into and out of mesh with the gear forming part of the delivery mechanism of the bin, substantially as specified.

7. The combination of a storage-bin, mechanism governing the delivery therefrom and said delivery mechanism, and also having a bin for receiving material discharged from the storage-bin, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
